Brucellosis is caused by the bacterium Brucella and affects various domestic and wild species. GroEL (Heat Shock Protein 60kDa) as one of the major antigens that stimulate the immune system, increases Brucella survival. The aim of the current study was to clone and express GroEL in Escherichia coli in order to design subunit vaccine. Amplifying was performed using specific primers. The full-len...
chicken infectious bronchitis virus (ibv) causes severe respiratory and renal dysfunction in chickens. in the present study, we used reverse transcription-polymerase chain reaction (rt-pcr) to amplify the nucleocapsid (n) protein gene of strain massachusetts (mass) h120 of ibv that is commonly used in the vaccine production in iran. the pcr product with the expected size of 1.2 kb was cloned in...
Introduction: Enterohemorrhagic Escherichia coli (EHEC) and serotype O157: H7 is one of the most important diseases causing diarrhea. Shiga-like toxin secreted by the bacteria destroys epithelial cells and, in acute cases, causes hemolytic uremic syndrome (HUS). Antibiotic therapy is not effective against this pathogen, because it increases the production of Shiga toxin. Designing chimeric immu...
Objective(s): Helicobacter pylori, a human specific gastric pathogen is a causative agent of chronic active gastritis. The vacuolating cytotoxin (VacA) is an effective virulence factor involved in gastric injury. The aim of this study was to construct a recombinant protein containing antigenic region of VacA gene and determine its antigenicity. Materials and Methods: The antigenic region of V...
Rabies virus nucleoprotein (N protein) encapsidates genomic RNA of the virus and forms the viral ribonucleoprotein complex. These N proteins represent highly organized structures which activate proliferation of B cells and production antibodies against the N protein. In addition to the B cell, the rabies virus N protein has been shown to induce potent T helper cell responses resulting in a long...
Background and Objective : Bacteriophage vectors recently have been considered as a gene transfer and vaccine delivery vehicles chiefly due to their low cost, safety, and physical stability. Since, little is known about phage mediated gene transfer in mammalian hosts, A group of invitro experiments were performed to ascertain gene transfercapability of these vehicles . Materials and Methods...
Background: Root hair culture is a valuable system to produce recombinant proteins in planta. Antimicrobial peptides (AMPs) are vital parts of the innate immune response found in almost all forms of life. Precise target activity and limited toxicity towards mammalian cells make them suitable candidate molecules to combat evolving drug-resistant microorganisms. The aim of the present study...
background: recombinant vaccine technology is one of the most developed means in controlling infectious diseases. however, an effective vaccine against shigella is still missing. objective: to evaluate recombinant ipac protein of shigella as a vaccine candidate. methods: in this study we cloned ipac gene into an expression vector in prokaryotic system. the protein expression was evaluated by sd...
background : amelogenins are the major components of enamel matrix proteins. enamel matrix derivatives (emd) can be used in periodontal diseases to regenerate periodontal tissues. the main aim of this study was to evaluate ex-pression of full-length functional recombinant human amelogenin (rham) in iranian lizard leishmania (i.l.l.) as an alternative eukaryotic expression system. methods : huma...
Regarding high potential of green plants for development of recombinant vaccines, this research was conducted to evaluate expression of a novel recombinant vaccines against Foot and Mouth Disease (FMDV) in tobacco plant. For this purpose, a synthetic gene encoding 129-169 amino acids of foot and mouth disease virus capsid protein VP1 was transferred to tobacco plant via Agrobacterium-mediated g...
